Senile atrial fibrillation

Atrial fibrillation (AF) is one of the most common arrhythmias. It is an atrial rhythm characterized by disordered atrial excitation and ineffective contraction, caused by many small reentrant circuits originating from an atrial-dominant reentrant loop, leading to atrial rhythm disorder. It is very common in the elderly. It is seen in almost all organic heart diseases and can also occur in non-organic heart diseases. Atrial fibrillation has a high incidence, long duration, and can cause serious complications such as heart failure and arterial embolism, leading to increased disability or mortality, seriously affecting human health.
